Carry mechanisms for calculating machines

ABSTRACT

Carry transfer mechanism for mechanical registers of calculating machines, including such mechanism capable of performing two primary transfers in a single registration. Two primary transfers may occur, when a units and tens of an integrated partial product are registered in a single order of a register that already indicated a number, for example the units amount (9) of one order may be integrated with a tens amount (8) of the next lower order and in one motion the integrated amount (17) may be entered into one register order that stands at more than 3 (4 for example), and, for the register to indicate (9+8+4), the one register order is rotates twice past primary transfer position and the next higher order of the register unit must be advanced twice in one registration operation. A mechanism cooperating with the above mechanism for completing simultaneously any consecutive transfers that may not normally be complete at the end of a registration operation. Simultaneous transfer mechanism for operating outboard orders of a carriage borne register. Simultaneous transfer mechanism for a counter that may also register quotients and multipliers.

An ordinally arrangedseries of register wheels, a reciprocatory transfer actuator for eachwheel operable from a normal position to an operated position and backto normal position, a detaining means engaging each said actuator foryieldably holding each said actuator in normal position, a commonreciprocatory drive means for said actuators normally standing in thepath of operation of said actuators and operable out of normal positionaway from said actuators in a forward stroke and operable back to normalposition toward any operated said actuators in a return stroke ofoperations, and a normally disabled connecting means adjustable uponmovement of each wheel from a first to a second given registeringposition to connect the actuator of the next higher order wheel to saiddrive means for a forward stroke operation of a thus connected saidactuator together with said drive means in a primary transfer operationand thereafter restoration of any operated said actuators to normalposition is positively controlled by said drive means.
 52. In a registerincluding an ordinally arranged series of register wheels, a pivotalreciprocatory transfer actuator for each wheel comprising a lever armshiftable in a first direction from a normal position in a forwardstroke and shiftable in a second direction from operated position tonormal position in a return stroke of operations for imparting likemovement to its said actuator, a detaining means engaging each saidactuator for yieldably holding each said actuator and its said arm innormal position, a common pivot support shaft for said actuatorssituated transverse said wheels, a common reciprocatory drive bail meansfor said actuators comprising a rod transverse said actuators normallyblocking forward operation of said arms and therefore said actuators andbeing normally ineffective in its forward stroke in said first directionaway from said arms of said actuators and being effective at the end ofits return stroke in said second direction for blocking all of said armsand said actuators in normal position, normally disconnected hook meanspivotally mounted on each said arm and being shiftable from ineffectiveposition to rod engaging position for connecting each said arm to saidrod for forward stroke operation of said actuator therewith in a primarytransfer operation, and means operable upon movement of each wheel froma first to a second given registering position to shift the said hookmeans for the actuator of the next higher order wheel into engagementwith said rod.
 53. The combination according to claim 52 wherein saiddrive bail means includes bail portions secured to said rod and mountedon said shaft for arcuate reciprocation of said rod about the axis ofsaid shaft, said arms and said actuators.
